IMPROVEMENT IN MUClLAGE-BRUSHES.

Specification forming part of Letters Patent No. 212,904, dated March 4,1879; application filed November 8, 1878.

To all whom it may concern:

Be it known that I, JOHN B. DAVIDs, of the city, county, and State ofNew York, have invented a certain new and useful Improvement relating toBrushes, whereof the following is a full, clear, and exact description,reference being had to the accompanying drawings, which form a part ofthis specification.

This invention relates to that class of brushes known asfountain-brushes, in which the mucilage or other liquid is supplied tothe brush by means of a reservoir connected therewith.

The improved brush is especially adapted for use with mucilage-bottles,but may be employed for applying shoe-dressing, varnish, colors, andother liquids.

The invention consists in a fountain-brush composed of an elastic bulbor reservoir, a cap, a brush, and a tube extending from the clastic bulbto the brush, the said cap being placed between the elastic bulb andbrush, and adapted to support the brush and its reservoir in the mouthof a bottle or mueilage-holder; also, in a peculiar construction of thesupportingcap, and also in the construction of the tube for holding thebrush and for supplying the liquid thereto, it being provided withapertures in the sides for this purpose, as set forth in the claims.

The reservoir may be quickly and readily filled, and the supply ofliquid to the brush is under perfect control of the user, and it is atthe same time not liable to become clogged or get out of order, and mayalways be neat and clean.

The accompanying drawing forms a part of this specification, andrepresents what I consider the best means of carrying out the invention.It is an elevation partly in section.

A represents the cap to the mucilage-bottle, having on the upper surfacea projection or tube, a, provided with a flange, knob, or cap. B is thereservoir, in the form of a hollow elast-ic or rubber bulb, attached tothe tube a, the flange on the said tube preventing its ready removal. 0is the brush-holder, consisting of a tube attached at its upper end tothe under side of the cap A, and provided at the other end with thebristles D. The bristles D are held by clamping them between the sidesof the tube, but other approved means may be used.

Apertures d are made to admit the flow of mucilage into and out of thetube above D.

In operation, the bulb or reservoir is filled by compressing the same toexclude the air, then placing the lower end of the brush-holder so as tohold the holes cl below the surface of the mucilage or other liquid, andallowing the bulb to expand. The quantity of mucilage in the bulb may beregulated by raising the device when a sufficient quantity has beendrawn thereinto.

To supply the mucilage to the brush, the bulb is compressed more orless, according to the quantity of mucilage required.

The projection or neck on the upper part of the cap is extended upwardand the bulb is movable thereon, so that a longer handle may be given tothe brush by moving the bulb outward, or it may be better employed in aninclined or inverted position if the bulb is close to the cap, as shownin the drawing. It is evident, however, that the cap with a shorterprojection might be used in connection with the dependent brush.

One advantage of the length given to the part a lies in the abilitythereby to better hold the bulb B nearly filled with mucilage by itsgravity independent of the atmospheric pressure. This becomes importantwhen by age or other cause the top of the bulb B becomes cracked, so asto leak air. By sliding the bulb B down in the position shown it willretain the mucilage for any length of time, and it will be ready todeliver it by either sliding it up or sufficientlycompressingit, orboth. But some of the advantages of my invention can be secured with thepart a very short.

If desired, the upper part of the bottle-cap A may be formed with agroove surrounding the upper projection, as shown; but some of thebenefits of my improved device may be obtained without this feature.

I have described the bulb attached to a tube or projection from the topof the cap; but it is evident that the tube which forms the brushholdermay be extended through the cap, and

Instead of using the bristles or hair to form a brush, a piece ofsponge, cork, rubber, or other suitable soft material maybe secured inthe end of the tube 0; but I prefer the brush, as less apt to get out oforder.

I can make the cap A, the upper part of the tube a, and the lower part,0, all in one piece of cast metal; or I can make the tubular parts 0 anda in one piece of drawn tube or wrought material, and the cap A in softmetal or other suitable material cast thereon. I can make the entiremetal part of malleable cast-iron.

I can use one or more cross-bars instead of the close cap A. Anythingwhich will serve to keep the brush in the proper position when insertedin a bottle will suffice.

I am aware that a marking-brush has been made with an elastic bulb toserve as a reservoir for the marking-fluid. The present inventiondiffers from brushes of this kind in the supporting-cap between elasticbulb and brush, the said cap also being of peculiar construction, andalso in the mode of securing the brush in the tube, and of supplyingposes specified.

2. The tubular part 0, having side aperture 01 over the brush materialD, in combination with the latter and with the elastic bulb B of afountain-brush, as herein specified.

3. The device described, composed of the elastic bulb B, the prolongedand knobbed tubular top a, cap A, lower tube, 0, having one or moreholes, (I, and bristles D, adapted to serve with a mucilage-bottle, asherein specifled.

In testimony whereof I have hereunto set my hand this 4th day ofNovember, 1.878, in the presence of two subscribing witnesses.

JOHN B. DAVIDS.
